Abstract: 1,022,474. Discharge tubes. STANDARD TELEPHONES & CABLES Ltd. Nov. 23, 1962 [Nov. 30, 1961], No. 44408/62. Heading H1D. A high vacuum symbol display tube includes a phosphor display screen formed as a coating on the tube envelope and one or more cathodes, each comprising a metal base coated with electron-emissive material, e.g. magnesium oxide, for field emission of electrons. The or each cathode may be connected to earth through a discharge-blocking resistor which may be shorted out, so that after initial excitation, the cathode is maintained in an excited condition and caused to emit electrons when desired. The cathode may be initially excited by electron and photon bombardment from a heated filament or by irradiation with ultra-violet light or by the inclusion of radio-active material within the envelope. The tube may comprise a plurality of metal cathode bases 8, Fig. 3, secured to, or coated on, an insulator 7, the cathodes having raised emissive coatings 11, which may be selectively energized to display any of the Arabic numerals. A similar pattern of emissive cathode portions may be formed on wire cathode bases, Fig. 2 (not shown). An accelerating grid may be provided in front of the cathodes, the display screen being held at a lower positive potential. The phosphor screen may be divided into parallel strips 20, Fig. 6, extending at right angles to linear emissive portions 19 on ring-shaped cathode bases, to produce a matrix raster. The use of ring-shaped cathode bases facilitates eddy current heating thereof during tube manufacture.

Title: Injection-molding machine and unthreading means therefor
IPC: B29D1/00
Filed: 1965-10-22
Abstract: 1,075,719. Injection moulding machines. HUSKY MANUFACTURING & TOOL WORKS Ltd. Oct. 22, 1965 [Oct. 23, 1964], No. 44827/65. Heading B5A. In a machine for injection moulding screw-threaded articles, one mould part can be swung laterally out of alignment with the remaining mould part or parts into an unthreading position at which an unthreading device 14 is movable towards and away from the mould part. As shown, the machine comprises a fixed mould part 27, a mould part 28 mounted on a holder 15 slidable on bars 16, 17 and a mould plate 31b mounted on the bar 17 for rotation and sliding motion. The mould plate 31b is mounted diagonally opposite a similar plate 31a (Fig. 3, not shown) the two plates being displaceable through 180 degrees about the bar 17 by rack-and-pinion mechanism (75, 76) (Fig. 2, not shown) driven by an electric motor 65. The moulded articles may be internally or externally screw-threaded. The unthreading device 14 may be mounted on either of two pedestals 80 (only one visible in Fig. 1) depending on the direction in which the articles must be unthreaded. Up to, e.g. twenty-four articles may be moulded simultaneously but the machine shown moulds four articles 32 in apertures 33 (Fig. 3, not shown). For unthreading, spring-urged rubber cups 86 (Fig. 4, not shown) are moved into engagement with the articles, the cups 86 being rotatable by an electric motor 105 through gearing (96, 97, 100, 99, 102, 103). To and fro movement of the cups 86 is effected by a lead-screw (111) rotated by the motor 105 and engaging in a nut (113) held fast in a member (115) connected through a member (116) and bars (83, 84) (Fig. 5, not shown) with a plate 82 carrying the cups 86. The members (115, 116) are biased apart by springs (117) but can be moved together by pneumatic cylinders and pistons (120-123), thereby bringing the cups 86 into frictional engagement with the moulded articles. After the articles have been unthreaded the springs (117) move the members (115, 116) apart again and the articles are ejected from the cups 86 by plungers (92) (Fig. 4, not shown). A speed changer (not shown) may be included between the motor 105 and the pinion 103 to give slow initial unthreading and then a faster rate. A pump 43 supplies cooling liquid through flexible hoses 39, 41 to channels (not shown) in arms (34a, 34b, 35a, 35b) (Fig. 3, not shown) carrying the mould plates 31a, 31b and also to cooling channels (46) in a hub (45) (Fig. 6, not shown). The machine may be under automatic, semiautomatio or manual control.

Abstract: 1531447 Three port circulator PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 31 Oct 1975 [14 Nov 1974] 45301/75 Heading H3U A three port circulator circuit substantially as shown, with transistor equivalents, Fig. 4, as alternatives to the transistors 10, 11 has the capability of using any impedance at 15, 12, 13, 16 instead of the resistors shown. Signals are transferred from port one 2,1 to port three 5,6; from port three to port two 3,4 and from port two to port one. By connecting the base of transistor 11 through an impedance (14, Fig. 2, not shown) to the supply terminal the resulting two port is a gyrator. If this impedance is a resistor in series with a number of semiconductor diodes (20, 21, 22) then it is stated that the circuit is rendered independent of the slope of the transistors. To render it independent of frequency, a capacitance 17 may be connected. The resistors may be replaced by more complicated impedance elements (not shown) to compensate for phase shifts in the transistors. Instead of the resistor 16 a transistor (23, Fig. 5, not shown) can be used stabilized by a diode (21) parallel to the emitter-base and a further diode (20) and resistor (18) in series. When the gyrator is used to form a tuned circuit, the resultant Q can be improved by an extra transistor (22, Fig. 5, not shown). The capacitance 26 connected at the first port 1, 2 being rendered as an inductance at the second port 3, 4 where it is resonated by the external capacitance 16. It is stated that the network can be readily constructed in integrated form.
